ABSTRACT: The central compartment of the nuclear pore complex (NPC), allowing the nuclear-cytoplasmic transport of molecules, consists
of transmembrane proteins which anchor the pore in the nuclear envelope. Morphological and morphometric analyses of nuclear
pore organization in Saccharomyces cerevisiae with mutations in the POM152 and POM34 genes have been performed. The absence of Pom152 or Pom34 initiates the disruption of the nuclear pore complex assembly.
As a result, their quantity in the nuclear envelope decreases. Electron-microscopic examination shows that the inhibition
of POM152 expression is also accompanied by an increase in the NPC inner diameter not observed in mutant cells with Pom34 depletion.
